PHP scripts started failing

Question

At some point during maintenance YMP2-TS8 all of my php scripts started failing with "The page cannot be displayed because an internal server error has occurred.". I created an HTML file that worked then changed the extension to .php and now I get that internal server error (https://www.textmuse.com/zivoz/demo/test2.html, https://textmuse.com/zivoz/demo/test2.php). There are no errors in php_errors.log.

I would try Enable diagnostics logging for apps in Azure App Service to better determine what the issue is. If you a simple HTML file works but your PHP file doesn't, it may be an issue with the script. Just curious if a plain Jane PHP file worked e.g.

   <?php  
     
   echo "This is a test";  

If you're running your PHP app on Linux, try accessing the docker logs via https://<appname>.scm.azurewebsites.net/api/logs/docker to determine if there were any PHP errors during image retrieval and app startup. PHP on Linux plan uses PHP 8 so there may be an incompatibly there; highly unlikely but without additional logging information not outside the realm of possibility.
